Hydroxyethyl Cellulose oildrilling
Hydroxyethyl Cellulose
Overview
Hydroxyethyl Cellulose is an non-ionic water-soluble polymer, it is white to slightly yellow, odorless and tasteless powdered solid. It is mainly used as viscosifier and fluid loss agent in oildrilling.
Specification
Type | Viscosity mpa.s | Moisture, % ≤ | Ash, % ≤ | pH |
O300 | 150-400(2%) | 6.0 | 6.0 | 6.0~8.5 |
O100000 | 4500~6000(1%) |
Remarks: The above viscosity values are all obtained using Brookfield Viscometer at 25℃, LVTD.
Liquid Hydroxyethy Cellulose
Overview
Liquid HEC is made by mixing HEC, mineral oil and surfactant. It can be rapidly disperse in and thicken a variety of brines, including sea water and other light brines, with minimum shear and without forming fisheye.
